We all know how fast kids grow, but this fascinating accelerated time-lapse video follows a girl from birth to teen. What we as parents get to see in years, can now be viewed in just minutes.

What's amazing is how dramatically babies grow and change during the the first few years. Then, it seems the changes slow for a few years only to give way to more changes as children get closer to becoming teenagers.

It's also interesting to see there are certain features, like this girl's nose and eyes, that always seem to look the same no matter what the age.

Watching this may make you want to dig out all the photos and videos of you kids and see how much they changed as they grew.
